Counterweight module system for quick deepening of marine towing rope

Abstract

The invention relates to the technical field of marine towing ropes, in particular to a counterweight module system for quick deepening of a marine towing rope. The counterweight module system comprises a plurality of detachable counterweight module units, wherein the counterweight module units are fixedly arranged on the towing rope at equal intervals; each counterweight module unit comprises a first clamp block, a second clamp block, a rotary clasp, a fixed lug, a pin shaft, a first protective sleeve and a second protective sleeve; each first clamp block and the corresponding second clamp block are fixedly connected together through the corresponding pin shaft, and can rotate around the corresponding pin shaft; each rotary clasp and the corresponding fixed lug are respectively and fixedly welded in the middle parts of the corresponding first clamp block and second clamp block according to matching sizes; each first protective sleeve and the corresponding second protective sleeve are respectively arranged at clamping surfaces of two ends of the corresponding first clamp block and second clamp block. The counterweight module system has the advantages that by designing the quick clasps, a counterweight block and the towing rope are tightened, so that the installation and detachment time is greatly shortened; by distributing at equal intervals, the weight ratio of the towing rope can be uniformly adjusted, so that the array of the towing cable can meet the use requirements of towing, and the adjusting and use requirements of different towing depth at the same sailing speed can be met.

Description

technical field [0001] The invention relates to the technical field of ocean streamers, in particular to a counterweight module system for rapid depth change of ocean streamers. Background technique [0002] Generally, there are two ways to adjust the working depth of the towed cable: 1. According to the parameter calculation of the towed cable, adjust the speed of the operation ship; 2. Hang the counterweight at the tail of the towed cable to adjust. [0003] However, when using the first method: due to the inconsistency of the parameters of various towing cables, the setting of the towing work speed is different. When performing double towing work, the speed compatibility requirements are high, and the selection of the towing cables is subject to certain restrictions. limit. [0004] When using the second method, the balance weight is suspended at the tail to adjust, which requires high calculation of the weight ratio, and because the weight ratio is concentrated at the t...

Problems solved by technology

[0003] However, when using the first method: due to the inconsistency of the parameters of various towing cables, the setting of the towing work speed is different. When performing double towing work, the speed compatibility requirements are high, and the selection of the towing cables is subject to certain restrictions. limit

[0004] When using the second method, the balance weight is suspended at the tail to adjust, which requires high calculation of the weight ratio, and because the weight ratio is concentrated at the tail, although it can be roughly adjusted to the required depth, it will lead to inconsistencies in the formation of the towline. There is a gap, which cannot meet the requirements for use
